Constructors
SessionImpl
SessionImpl(
const std::string & fileName,
Poco::Any maxFieldSize = std::size_t (1024),
bool enforceCapability = false,
bool autoBind = false,
bool autoExtract = false
);
Creates the SessionImpl. Opens a connection to the database
Destructor
~SessionImpl
~SessionImpl();
Destroys the SessionImpl.
Member Functions
autoBind
void autoBind(
const std::string & param43,
bool val
);
Sets automatic binding for the session.
autoCommit
void autoCommit(
const std::string & param42,
bool val
);
Sets autocommit property for the session.
autoExtract
void autoExtract(
const std::string & param44,
bool val
);
Sets automatic extraction for the session.
begin
void begin();
Starts a transaction
canTransact
bool canTransact();
Returns true if connection is transaction-capable.
close
void close();
Closes the connection
commit 
void commit();
Commits and ends a transaction
createStatementImpl
Poco::Data::StatementImpl * createStatementImpl();
Returns an ODBC StatementImpl
dbc
const ConnectionHandle & dbc() const;
Returns the connection handle.
getEnforceCapability
bool getEnforceCapability(
const std::string & name = ""
);
Returns the driver capability check configuration value.
getMaxFieldSize
Poco::Any getMaxFieldSize(
const std::string & rName = ""
);
Returns the max field size (the default used when column size is unknown).
getQueryTimeout
Poco::Any getQueryTimeout(
const std::string & param46
);
Returns the timeout (in seconds) for queries, or -1 if no timeout has been set.
isAutoBind
bool isAutoBind(
const std::string & name = ""
);
Returns true if binding is automatic for this session.
isAutoCommit
bool isAutoCommit(
const std::string & name = ""
);
Returns autocommit property value.
isAutoExtract
bool isAutoExtract(
const std::string & name = ""
);
Returns true if extraction is automatic for this session.
isConnected
bool isConnected();
Returns true if and only if session is connected.
isTransaction
bool isTransaction();
Returns true if and only if a transaction is in progress.
maxStatementLength
int maxStatementLength();
Returns maximum length of SQL statement allowed by driver.
queryTimeout
int queryTimeout() const;
Returns the timeout (in seconds) for queries, or -1 if no timeout has been set.
rollback
void rollback();
Aborts a transaction
setEnforceCapability
void setEnforceCapability(
const std::string & param41,
bool val
);
Configures session to enforce driver capability check after connection. If capability check is enforced and driver is not capable, connection is terminated. Since some drivers do not cooperate, the default behavior is not checking capability.
setMaxFieldSize
void setMaxFieldSize(
const std::string & rName,
const Poco::Any & rValue
);
Sets the max field size (the default used when column size is unknown).
setQueryTimeout
void setQueryTimeout(
const std::string & param45,
const Poco::Any & value
);
Sets the timeout (in seconds) for queries. Value must be of type int.
